BOTTLE-SEALING DEVICE.

SPECIFICATION forming-part of Letters Patent No. 697,491, dated April15, 1902.

Application filed June 18, 1901.

To all whom it mayconoern:

Be it known that I, LEWIS KALLING, of the city of Baltimore and State ofMaryland, have invented certain Improvements in Bottle- Sealing Devices,of which the following is a specification.

This invention relates to certain improvements in the sealing-cap shownand described in Letters Patent No. 561,792, granted to me on the 9thday of June, 1896, for a bottle-sealing device, to which referenceshould be made. The said patented sealing-cap embodies a hollow beadformed in its cylindrical wall, the same producing an inner annulargroove, in which rests an annular j oint-formin g gasket, which as thesaid bead is flattened by the application to the cap of an annulardrawingtool, which may constitute a portion of a capping-machine, iscompressed tightly between the wall of the cap and the exterior surfaceof the bottle-head to effect a tight joint. By reference to the drawingsforming a part of the said Letters Patent it will be seenthat as theannular gasket has a larger diameter than the portion of the wall belowthe groove formed by the hollow bead it has to be compressed ordistorted from its annular shape in the act of its insertion in thegroove, and consequently it is difficult to introduce the gasket intothe cap by mechanical means.

The object of the present invention is therefore to produce a cap inwhich the gasket may be secured by machinery and preferably by means ofan apparatus shown and described in the application of Albert Jones, No.682,114,

"for a machine for producing bottle-sealing caps, filed on the 31st dayof May, 1898, to which reference should be made.

In the further description of the said invention which follows referenceis made to the accompanying drawings, forming a part hereof, and inwhich I Figure 1 is an exterior side view of the upper part of a bottleprovided with a sealingcap constructed in accordance with the presentinvention and showing the cap as resting loosely on the bottle-head.Fig. 2 is a central section of Fig. 1. Fig. 3 is aview similar to Fig.2, except that the cap is secured firmly in place on the bottle-head anda tight joint effected. Fig. 4 is an enlarged central section of thesealing-cap as it appears before Serial No. 65,045. (No model.)

the joint-forming gasket is secured therein. Fig. 5 is a view similar toFig. 4, showing the sealing-cap as it appears after the joint-forminggasket is secured therein. Fig. 6 is an under side view of Fig. 5.

Referring now to the drawings, 1 is the bottle-head, which is shown asslightly tapered from the top or lip, but which may be cylindrical orany other shape, if desired, as the present invention does not includeany particular formation of the bottle-head.

2 is the crown of the sealing-cap, which is shown as fitting theexterior lip 3' of the bot- 4 is the cylindrical wall of thesealing-cap, having an inner diameter which is considerably greater thanthat of the bottle-head in order to admit of the placing of thecompressible annular gasket 5 therein.

The sealing-cap as first formed is shown in Fig. 4:, and by reference tothat figure it will be seen that the annular gasket 5, which is insertedin the cap by means of the apparatus shown and described in the pendingapplication, before alluded to, is flush with the edge of the wall. Inanother and subsequent operation of the said apparatus the edge of thecap is turned in, as best shown in Fig. 5, to form the gasket-holdingbead 6, and in the act of forming this bead the gasket is pushed incontact with the crown 2 of the cap.

It will be understood that the finished sealing-cap diders from thatshown and described in the said Letters Patent in that its entireannular wall has to be flattened or reduced in diameter in thecap-affixing operation instead of a part only thereof.

The gasket when introduced into the sealing-cap is quite soft; but afterit is secured therein by heading the edge of the wall it is hardened byan ordinary vulcanizing process effected in a properly-constructedvulcanizing-oven; but the vulcanizing process forms no part of thepresent invention.

In the cap-affixing operation the annular wall of the cap is elongatedand reduced in diameter; but the drawing process whereby such change inthe shape of the cap is efiected does not remove the inturned bead fromcontact with the said gasket, for the reason that as the gasket isreduced in thickness its length is correspondingly increased IGO I claimas my inVentioncontact with the inturned bead, and which A sealing-capadapted for application to a annular gasket, as the said annular wall isbottle-head, which consists of a crown, and a reduced in diameter, inthe cap-allixing opcompressible cylindricalannularwalldepend eration, iscompressed so as to form a joint 5 ing therefrom, the said Wall havingits edge between the said walland theb0ttle-head,sub- I 5 provided withan inturned bead of an exterstantially as, and for the purposespecified.
